UTC Date/Time String to Timezone

如何将UTC的日期/时间字符串（例如2011-01-01 15:00:00）转换为php支持的任何给定时区，例如America / New_York或Europe / San_Marino。

PHP的DateTime对象非常灵活。

$UTC = new DateTimeZone("UTC");
$newTZ = new DateTimeZone("America/New_York");
$date = new DateTime( "2011-01-01 15:00:00", $UTC );
$date->setTimezone( $newTZ );
echo $date->format('Y-m-d H:i:s');

PHP's DateTime object is pretty flexible.

Since the user asked for more than one timezone option, then you can make it generic.

Generic Function

function convertDateFromTimezone($date,$timezone,$timezone_to,$format){
 $date = new DateTime($date,new DateTimeZone($timezone));
 $date->setTimezone( new DateTimeZone($timezone_to) );
 return $date->format($format);
}

Usage:

echo  convertDateFromTimezone('2011-04-21 13:14','UTC','America/New_York','Y-m-d H:i:s');

Output:

2011-04-21 09:14:00

Assuming the UTC is not included in the string then:

date_default_timezone_set('America/New_York');
$datestring = '2011-01-01 15:00:00';  //Pulled in from somewhere
$date = date('Y-m-d H:i:s T',strtotime($datestring . ' UTC'));
echo $date;  //Should get '2011-01-01 10:00:00 EST' or something like that

Or you could use the DateTime object.
